Height, weight, and blood pressures in ten-year-old children
Insights
Body mass index, height, and weight effectively predict blood pressure in 10-year-old children. These factors remain significant predictors regardless of puberty onset, aiding in pediatric hypertension assessment.
Area of Science:
- Pediatric Health
- Cardiovascular Research
- Biostatistics
Background:
- Accurate blood pressure measurement is crucial for identifying pediatric hypertension.
- Understanding anthropometric predictors of blood pressure in children is essential for early detection and intervention.
- Previous research has explored various anthropometric measures, but optimal predictive models for children require further investigation.
Purpose of the Study:
- To identify the most effective combination of anthropometric variables (height, weight, BMI) for predicting systolic and diastolic blood pressure in a national sample of 10-year-old children.
- To assess the influence of puberty on the relationship between anthropometric factors and blood pressure.
- To adjust for potential measurement bias introduced by sphygmomanometer cuff size.
Main Methods:
- Utilized multiple regression analysis on a national sample of 13,723 children aged 10.
- Evaluated height, weight, and body mass index (BMI) as predictors for systolic and diastolic blood pressure.
- Adjusted all analyses for the depth of the sphygmomanometer cuff used during measurement.
Main Results:
- For boys, systolic blood pressure was best predicted by weight, height, and height squared. For girls, weight divided by height squared and height were the strongest predictors.
- Diastolic blood pressure in boys was primarily predicted by weight alone. In girls, weight divided by height squared and height were the most significant predictors.
- No significant differences in blood pressure were observed between children with and without signs of puberty after accounting for the identified anthropometric predictors.
Conclusions:
- Specific combinations of height and weight provide the most accurate prediction of blood pressure in 10-year-old children, with variations between sexes.
- The predictive power of these anthropometric measures remains consistent, irrespective of pubertal status.
- These findings support the use of tailored anthropometric models for assessing blood pressure in pediatric populations.
Abstract:
Multiple regression techniques were used to determine the most efficient combination of height, weight and body mass index in the prediction of systolic and diastolic blood pressures for a national sample of 13,723 10-year-old children. In every analysis an adjustment was made for the depth of sphygomomanometer cuff used when taking the blood pressure. The variables which together best predicted the systolic blood pressures in boys were weight, height and (height)2, and in girls weight/(height)2 and height. Diastolic blood pressures were predicted best by weight only for boys and by weight/(height)2 and height for girls. Once these factors had been taken into account there was no difference in blood pressures in those children for whom there were signs of puberty.
